Chapel at Ursulines monastery, Baroque chapel in Brno-město, Czech Republic

The Chapel at Ursulines monastery has a rectangular plan with a semicircular apse and a gabled roof. Shallow pilasters and round-arched windows articulate the side walls, and a profiled cordon cornice runs around the whole building. The west facade is divided by pilasters, with niches capped by shell reliefs flanking the rectangular entrance, above which a stucco frame holds the Dietrichstein coat of arms combined with the Franciscan emblem. A triangular gable with an angel's head relief, volutes and two obelisks crowns the facade, topped by a double-armed cross.

The Franciscan nuns, forced inside Brno's walls by a siege, began building their convent from 1655; the chapel dates from the early 1670s, when sources record its dedication to Saint Mary Magdalene. After Emperor Joseph II dissolved the convent in 1782, the Ursulines took over the complex until their own dissolution in the 1950s. The Technical Museum later restored the chapel, and after 1989 the grounds returned to the Ursulines, who sold the convent to the Brno bishopric.

The chapel's current name comes from its 18th- or 20th-century interior, which imitates a grotto with statues of Christ praying before an angel and sleeping apostles. The original dedication was to Saint Mary Magdalene. The space is normally closed and opened to the public during events such as the 2021 Night of Churches.

The chapel typically remains closed to regular visitors but opens during special events such as the Night of Churches. Travelers planning to visit should check ahead for upcoming events at the monastery complex to make the most of access opportunities.

A weathered limestone tombstone of Brno goldsmith Josef Achbauer (1717–1788) stands outside the chapel's south wall, by the hedge, not inside. It is a slender column topped with a vase; the Latin inscription records his children Jan Nepomuk and Róza and a probable reburial on 6 August 1808. It likely came from the vanished city cemetery on today's Kounicova Street.
